CBD has been identified as a possible weapon in the battle to halt the spread of COVID-19.

Researchers at a Canadian university found that extracts high in CBD may increase resistance to the virus by restricting its ability to enter the lungs.

Data suggests a limited sample of CBD Cannabis sativa extracts hinder what is known as Angiotensin-converting enzyme 2 (ACE2), the receptor for the entry of COVID-19 into human cells.

The study sifted through 400 strains of cannabis of which around a dozen displayed promise.

Dr Igor Kovalchuk: “Our investigations warrant further investigation”

The encouraging results were unveiled by research firm Pathway RX which conducted the study at the University of Lethbridge in Alberta in collaboration with cannabinoid oral health developer Swysh.

Research papers have been submitted to a scientific journal for peer reviews.

“Our initial findings warrant further investigation but it’s possible that medicinal cannabis products could become a safe adjunct therapy for the treatment of COVID-19,” Pathway chief executive Dr Igor Kovalchuk said.

He told the Calgary Herald how the promising cannabis strains reduced the number of virus receptors by 73%.

“If they can reduce the number of receptors there’s much less chance of getting infected,” Kovalchuk was quoted as saying.

The study was conducted using artificial human 3D models of oral, airway and intestinal tissues.

Israeli researches are also analysing the potential of cannabis with clinical trials set to explore whether CBD can repair cells damaged by coronavirus.
